Stem cells are currently the main hope for recovery and reconstruction of injured brain tissue. Type of stem cells preferable in brain injury are neural stem cells. The study and understanding of the interactions between neural stem cells and biomaterials can improve survival and fusion with injured or diseased areas of the central nervous system. Because of its biocompatibility, the hydrophilic character, the mechanical properties and structural diversity, hydrogels are widely used for regeneration of nerve tissue. The aim of this research is to examine whether methacrylated gellan gum (MGG) can be used as a good hydrogel carrier of neural stem cells, which would provide a range of possibilities of applications in neuroscience. To test this, we match mice neural cells in hydrogel gellan gum and measure the degree of multiplication (proliferation) cells five days after switching. Variations in survival and declining cells showed that 1% MGG is not suitable for neural stem cells.
